What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background/objectives: To investigate the demographic features, primary endoscopic findings, and the status of Helicobacter Pylori (H. pylori) infection of the enrolled subjects who underwent upper gastrointestinal endoscopy (UGIE) in the Zanzibar Archipelago, Tanzania. Methods: Between December 2013 and October 2021, a total of 3146 eligible participants were finally recruited in present retrospective cohort. Demographic information and endoscopic findings of each participant was retrieved. H. pylori infection was confirmed by rapid-urease test of gastric antral and body biopsies at endoscopy. Results: Among the recruited subjects, 1691 (53.76%) are females, remaining 1455 (46.24%) are males. The median age of this retrospective cohort was 40 years ranging from 8 to 97 years. The common identified endoscopic findings included gastro-duodenitis, normal endoscopic finding, peptic ulcer disease (PUD), esophagitis, esophagogastric varices, esophageal and gastric cancer, respectively. After adjustment for sex and age, a significant risk of gastric and/or duodenal ulcer (OR, 2.51; 95% CI, 1.82-3.48, P<0.001) and gastric cancer (OR, 3.49; 95% CI, 1.27-9.58, P=0.015) in H. Conclusions: The present study revealed that gastro-duodenitis, PUD, and normal finding are the most common endoscopic diagnoses in Zanzibar. The presence of H.
